THOMAS A. OROWEIJL, OF BOSTON, MASSACHUSETTS.

SEED AND CORN PLANTER.

SPECIFICATION forming part of Letters Patent 1\To. 230,244, dated July20, 1880.

Application filed April 3,1880. (N0 model.) I

To all whom it may concern Be it known that I, THOMAS A. CROWELL, ofBoston, in the county of Suffolk, and in the State of Massachusetts,have invented certain new and useful Improvements in Seed and CornPlanters; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

My invention relates to that class of seedplanters in ,which a rotatinghopper is employed; and it consists in providing a cylindrical rotatinghopper having a series of equidistant seed-openings with a laterally andaxially adjustable band which may be moved so as to uncover all theopenings in the hopper, and turned so as to uncover only three or fiveof said openings, or any other desired number, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure l is a central longitudinal section of my invention. Fig. 2 is aside view of the same.

A represents a cylindrical rotating hopper for seed-planters, providedwith fifteen seedopenings, at a, arranged in a circle around the centerof the hopper, at equal distances apart. Around this drum or hopper isplaced aband, B, which has two slots, 1) b, on two opposite sides.Through one of these slots, on each side, is passed a screw, (1, intothe hopper, which screws prevent any axial movement of the band, Whilethey permit a lateral movement, so as to cover or uncover theseed-openin gs a. p

In the band B are made two sets of openings, m and a. The openings inare three in number, and the openings at are five in number,

each being equidistant and so arranged with relation to the slots 1) bthat when the screws (1 d are in the slots 1) b the band may be moved tocover all the seed-openings to except three.

By removing the screws d and turning the band axially, so as to replacethe screwsin the same holes in the hopper through the slots 1), the bandwill be so adjusted that five openings in the hopper will be uncovered.

It will thus be seen that with a drivingwheel fifteen feet incircumference I can, with the same hopper, drop the seed one foot apart,three feet, or five feet, as desired.

If the hopper is made with, say, twelve seedopenings, the hand may bemade with three sets of holes to drop two, three, or four times for eachrevolution, in which case the band should have three sets of slotsjustmen t.

I am aware that a rotating seed-hopper with an axially adjustable bandhaving vaiying openings is not new; and I do not claim such, broadly, asmy invention; neither do I claim a rotating seed-hopper provided with aband that is laterally movable for opening and 010s ing theseed-openings in the hopper, as I am aware that such is of itself notnew.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A cylindrical rotating seed-hopper provided in its periphery with aseries of equidistant seed-openings and with a laterally and axiallyadjustable band provided with two or more sets of openings of unequalnumber, the openings of each set being equidistant, substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of March, 1880.
